Billy's a total proponent of RMI. However, he also practices RMIM and IMR just for the workout. Says he practices pretty much everything forward, backward, and inside out - literally.
If I'm doing straight fast passages, definitely RMI. If I'm just grooving, I don't follow a pattern. I'll do IM or IR at times too for the exercise or if it just feels right.
The gallop goes away, just takes a lot of repetition (like everything else). Building up the muscles and callouses to as almost even as possible.

But then, I don't practice 3 fingers so it's kind of a moot point lol 
and always have same question about IMR and IMRM
